MOSSBERG-77 - TESTS WITH CEMENT STABILIZATION ON HIGHLY FROST SENSITIVE UNDERGROUND. PROGRESS REPORT (MOSSBERG-77 - PROV MED CEMENSTABILISERING PA STARKT TJAELFARLIG UNDERGRUND. LAEGESRAPPORT 1979-11)

In 1977, on route 929 a test road was built in connection with a road reinforcement project including ground stabilization by cement. The test road includes 7 test sections and 1 reference section. The purpose of the test road is to study the relative importance of thickness and durability (cement quota) of the stabilized cement layer, primarily the development of bearing capacity over time and the risk of damage, affecting bearing capacity, in cases of higly frost sensitive underground. Bearing capacity has been studied continuously during the last 2 years by using test loads and by analyzing the medium modules and the stabilizing layer's modules. The medium modules, in particular, show that bearing capacity has declined somewhat over the period. Furthermore, it is obvious that the thickness of the stabilizing layer, so far, has had a considerably larger significance for the bearing capacity than the cement quota. Measurements have shown a modest (around 10 percent) but clear deterioration in the test road's levelness. The frequency of cracks has increased successively, but they have not yet resulted in perceptible damage affecting the bearing capacity.
